Abstract
A method for determining and/or monitoring a concentration of maltodextrin and/or maltose in a mashing process comprises method steps as follows: providing a mash, heating the mash to at least one predeterminable temperature, determining the density of the mash determining the velocity of sound in the mash, ascertaining a concentration of maltodextrin and maltose in the mash, and ascertaining the concentration of maltodextrin and/or maltose in the mash.
Claims4
A method for determining and/or monitoring a concentration of maltodextrin and/or maltose in a mashing process, comprising:
- providing a mash;
- heating the mash to at least one predeterminable temperature;
- determining the density of the mash;
- determining the velocity of sound in the mash;
- ascertaining a concentration of the sum of maltodextrin and maltose in the mash based on the density;
- ascertaining a ratio of maltodextrin and maltose based on the velocity of sound;
- and
- ascertaining the concentration of maltodextrin or the concentration of maltose based on the ratio;
- wherein
- a sensor unit is excited by means of a excitation signal to execute mechanical oscillations,
- the mechanical oscillations are received by the sensor unit and converted into a first received signal,
- a transmitted signal is transmitted from the sensor unit and a second received signal received by the sensor unit, and
- density is ascertained based on the first received signal and velocity of sound is ascertained based on the second received signal;
- wherein the mechanical oscillations and the transmitted signal are produced by the same piezoelectric element of the sensor unit;
- wherein the first received signal and the second received signal are different signals.
